WINDOW-CLEANER.

Application led February 12, 1908. Serial-No. 415,537..

' To all whom 'it may concern:

Be it known that I, HERMANUs JoHANUs SPOORENDONK, a citizen of the United States, residing in New York city, in the county and State of New York, have invented a new and useful Improvement in Window-Cleaners, of which the following is a specification.

This invention relates to a device for cleaning the outsides of windows, and while the device can be used upon any Window it is especiallyfadapted for use upon thefwdndows of cabs, locomotives, and upon the cab windows carried by the vestibules of motor cars. It is very desirable that the windows upon locomotive cabs and the from Windows upon car vestibules be kept free from smoke or fog so that the engineer or motorman can have a clear view of the track ahead of him. At certain seasons of the year this is almost impossible with the present construction of windows unless the windowis lowered,which deprives the en inee'r or motorman of rotection during t e season of the year W en he is most in need of it.- i

By means of the invention hereinafter described the outer face of thev Window pane can be wiped from Withinl the car and without opening the window.

In the accom anying drawings,-Figure l is 4a front elevatlon showing the device in osition. Fig.,2 is a vertical sectional view taken through a window and through my device.v Fig. 3 is a horizontal section on the line 3-3 in Fig. 1. Fig. 4 is a detail end view of the wiper. Fig. 5 is a cross section through a drum.

In constructing and applying the invention, I place upon the outer side of the window frame vertical rack bars 1 upon which travel pinions 2 mounted upon a shaft 3, which shaft carries a rubber roller 4, which roller is provided with a series of spiral] arranged rlbs 5. Between these ribs are tted wooden strips 6 which tend to strengthen them.' The shaft 3 is journaled loosely in plates 7 and said plates are supported by cords 8, which may be of a'ilexible wire or any other suitable material, and these cords are Wound upon spring actuated drums 9, said 'drums being carried bythe car or cab at any suitable point above the window and each is provided with a spring 9a.

As shown in the drawings the window f frame is offset so that it projects slightly inwardly and to the plates 7 are connected also cables 10-which pass downwardly through said frame, and if desired the cables 10 may be formed of wire sufficiently rigid to act as guide bars for the shaft 3, the openings in the window frame through which said guide cables 10 pass holding the moving parts of the device' into proper relation with the. window. l It will also be obvious that when the device is used upon the front windows of either a car or engine cab a rapid forward movement of the car orengine' will of itself create an air pressure'upon the wiper which will tend to hold it in contact with the window ment with their respective rack bars. he lower ends of the guide cables 10 are there- L suitable handle 11. l wardly upon the handle the wiper is drawn downwardly over the outer face of the window pane, and when downward pressure is relaxed the cables 8 will be rewound upon the springactuated drums and the wiper again lifted to its normal position at the top o the window.

obvious that one continuous drumwill answer thesame purpose and be the e uivalent ofthe single drum with the centra portion removed.

Thumb bolts 12 working throu h brackets 13 mounted uponthe window rame 4have their inner ends bearing on end portions of ressing them against the window sash, by

oosening said thumb bolts the lock bars can be removed.'

Having thus fully described my invention,

Letters Patent isl 1. AA device of the kind described comprising rack bars arranged adjacent the sides of and upon the outer face of a window, a rotatable wiper, pinions carried by said wiper engaging the rack bars, spring .actuated drums arranged above the window, cables winding upon said drums and supporting the wiper, ,as and for the purpose set forth.

2. A window wipercomprisi-ng a shaft, a rubber roller carried by said shaft and havi position relative to eachother, rack bars arwhat I claim as new and desire to secure toy thereby holding the pinions 2 into engagefore within the cab and are connected by a l By pressing down- While I have shown two drums it will be A the rack bars 1 and lock them in position by c,

ing spirally arranged ribs, wooden strips iitting between said ribs and holding them in Aranged adjaentza Window, pinions on the plates do Wpwardly, as and for the purpose shaftdengaging slxaid rack bars, spring aetuset forth. ated 4rums cab es r'nnug over said drums plates suspended from said cables, the shaftJ .HERMMUS JOHALUS SPOORENDOH' above mentioned being loosely journaled in Witnesses:
